Pivotal connection of a table leg to a frame

ABSTRACT

A table includes a table top, a frame, and a pair of non-circular openings are formed in the frame. The table also includes a leg that is movable between an extended position and a collapsed position relative to the table top. A connecting rod connects the leg to the pair of openings in the frame and the connecting rod preferably has a non-circular cross-sectional configuration. The connecting rod and the openings in the frame are sized and configured to loosely attach the leg to the table when the leg is in the collapsed position. The connecting rod and the openings, however, are sized and configured to securely attach the leg to the table when the leg is in the extended position.

The present application claims priority to and the benefit of U.S.Provisional Patent Application Ser. No. 60/371,486, entitled UTILITYTABLE WITH BLOW-MOLDED TABLE TOP, which was filed on Apr. 9, 2002, andis hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is generally related to tables and, in particular,to tables with blow-molded plastic table tops.

2. Description of Related Art

Many different types of tables are well known and used for a variety ofdifferent purposes. For example, conventional tables may include legsthat are pivotally attached to the table top and the legs may be movablebetween a use position in which the legs extend outwardly from the tabletop and a storage position in which the legs are folded against thetable top. Large, portable tables with folding legs are often referredto as “banquet tables” and these tables are often used in assemblyhalls, banquet halls, convention centers, hotels, schools, churches, andother locations where large groups of people meet. Because the tablesare portable, the tables can be positioned in an assortment of differentconfigurations and used in a variety of settings. When the tables are nolonger needed, the tables can be moved or stored.

Banquet tables are often used by various organizations and groupsbecause they allow effective and efficient use of space. For example,banquet tables may be used in large multi-purpose areas such as schoolgymnasiums, meeting halls and hotel conference rooms to allow groups ofpeople to meet. After the meetings are completed, the tables can befolded into a storage position and stowed in a relatively small space.This allows the gymnasiums, meeting halls and conference rooms to beused for other purposes. Thus, banquet tables allow groups andorganizations to efficiently use a particular space.

Conventional banquet tables with legs that are foldable between a useposition and a storage position may also be used in a variety of otherlocations. For example, these known tables may provide immediate tablespace and/or workspace in a house, apartment, garage, tool shed, and thelike. The foldable legs allow the tables to be conveniently set up,taken down, stored and transported whenever and wherever the userchooses.

It is known to construct conventional banquet tables from relativelyheavy materials such as wood or metal, which makes the tables heavy anddifficult to move. In particular, the table tops of conventional banquettables are often made from fiber board, particle board, or plywood, andthese known table tops may include a plastic or Formica-type surfacelaminated onto the upper surface of the table top to create a workingsurface. Disadvantageously, many of these conventional banquet tablesare not very strong and are unable to support a desired amount ofweight. In order to increase the strength of these tables, thicker andheavier table tops are often used. Unfortunately, the thicker andheavier table tops further increase the weight of the tables. As aresult, many conventional banquet tables with wooden table tops areundesirably heavy, and two or more people are often required to move thetables.

In order to prevent the middle portion of conventional banquet tablesfrom sagging, it is known to attach a metal frame to the bottom surfaceof the wooden table top. These known metal frames often included twoside rails that extended along the longitudinal length of the table topand the metal frames are frequently attached to the table top by aplurality of screws. Disadvantageously, the structural integrity of thetable top may be decreased by the holes created by the plurality ofscrews, and this may allow the table to collapse and fail. In addition,because the screws are typically individually attached to the table top,that may significantly increase the amount of the time required toconstruct the table.

Conventional banquet tables are often six or eight feet in length andtwo or three feet in width. Thus, banquet tables are often difficult tomove because of their large size and inherent bulkiness. In addition, asdiscussed above, these conventional banquet tables are often heavy.Accordingly, if these unwieldy and heavy conventional tables areinadvertently dropped, tipped over, or mishandled while moving or usingthe tables, then injury could result.

It is known to construct banquet tables from plastic or otherlightweight materials in an attempt to decrease the weight of thetables. Many of these lighter-weight tables, however, lack the strengthand sturdiness of the heavier-weight tables. Thus, many lighter-weighttables require complex support mechanisms and one or more support bracesto increase the strength and sturdiness of the table, which undesirablyincreases the weight and complexity of the tables.

Conventional banquet tables generally include legs that are attached tothe table tops by a number of mechanical fasteners such as screws orbolts, whether the table tops are constructed from wood, plastic ormetal. Disadvantageously, attaching the legs to the table tops by screwsor bolts creates a number of holes in the table tops. As discussedabove, these holes may decrease the structural integrity of the tabletop and may create undesirable stress concentrations in the table top.The holes may also create weakness or failure points that allow thetable to give way and collapse. It is also known to bond the table legsto the table top by adhesives such as glue, epoxy resins or othersuitable types of bonding agents. The bonding of the legs to the tabletop, however, may decrease the structural integrity of the table top.Significantly, if the mechanical fasteners or adhesive connection of thelegs to the table top fails, then the table may collapse. Theseconventional tables may be difficult to fix or repair, especially if theleg attachment portion of the table top is damaged or pulled away fromthe remaining portion of the table top.

The use of mechanical fasteners to attach the legs to the table topundesirably increases the number of parts required to construct thetable, which may increase the time required to assemble the table. Inaddition, many conventional tables required the legs to be positionedagainst the underside of the table top and then attached to the tabletop by the mechanical fasteners or glue. This increases the difficultyof the manufacturing process because the legs and table top must firstbe held in the desired positions and then the legs must be fastened tothe table top. In particular, if mechanical fasteners are used to attachthe legs to the table top, mating surfaces such as holes in the legs andcorresponding threaded openings in the table top must be carefullyaligned before the legs can be attached to the table top. Accordingly,many conventional tables require one or more persons to hold the legsand table top in the desired locations, and another person to fasten thelegs to the table top. This process is undesirably time consuming andlabor intensive. Alternatively, a single person may be used to attachthe legs to the table top, but this process is difficult to performrapidly and without any errors.

It is also known to use complex attachment mechanisms to facilitateattachment of the legs to the table tops. Disadvantageously, thesecomplex attachment mechanisms are generally heavier, more difficult toinstall, and more expensive. In addition, these complex attachmentmechanisms are often more difficult to use than conventional mechanicalfasteners or adhesives.

These disadvantages are often compounded because conventional tableswith folding legs typically require separate and distinct attachmentmechanisms for attaching each leg or a pair of legs to the table top.That is, because most conventional banquet tables include a leg or apair of legs attached to each end of the table, a number of holes orattachment points are required to attach the legs to the table top.Accordingly, many conventional tables have two or four separate pointsof attachment in order to attach the table legs to the table top. Thus,conventional banquet tables often include a plurality of holes in eachend of the table top, and these holes may undesirably allow the table tofail.

BRIEF SUMMARY OF THE INVENTION

A need therefore exists for a table that eliminates the above-describeddisadvantages and problems.

One aspect of the invention is a table including a table top and legsthat are movable between a first position in which the legs extend awayfrom the table top to allow the table to be used and a second positionin which the legs are positioned near the table top for storage.Advantageously, the table top and legs create a strong, sturdy andsecure table that can be used to support a wide variety of objects andthe table can be used for many different purposes.

Another aspect is the table top is preferably constructed fromblow-molded plastic to allow a lightweight table to be constructed.Significantly, if the table top is constructed from blow-molded plastic,it can easily be formed into any desired configuration, shape, size anddesign depending, for example, upon the intended use and/orconfiguration of the table. The blow-molded table top is also generallyweather resistant and temperature insensitive, which allows the table tobe used in a wide variety of locations and environments. In addition,the blow-molded table top is durable, long-lasting, and it generallydoes not corrode, rust or otherwise deteriorate over time. Further,because the blow-molded table top is relatively strong, it can be usedto support a relatively large amount of weight. Significantly, theblow-molded table top may form a structural member of the table, or thetable top may be supported by a frame.

Advantageously, the blow-molded plastic table top is relatively strongbecause it includes two or more opposing walls or surfaces that areseparated by a given distance. The opposing walls help create ahigh-strength, rigid table top. In addition, because the interiorportion of the table top is generally hollow, that creates a lightweighttable top. Thus, the blow-molded table top is both lightweight andstrong.

Still another aspect of the table is the table top may include one ormore depressions, “tack-offs” or “kiss-offs.” The depressions, whichextend from one surface towards another surface, are desirably sized andconfigured to increase the strength and/or rigidity of the table top.Preferably, the depressions extend from one surface and contact orengage an opposing surface, but the depressions do not have to contactor engage another surface. The depressions are desirably formed in thebottom surface of the table top so that the depressions are generallynot visible. The depressions, however, may be formed in the top surfaceand/or any other suitable portions of the table top. For example, one ormore depressions may be formed in the top surface of the table top andone or more depressions may be formed in the bottom surface of the tabletop, and these opposing depressions may be generally aligned. At least aportion of these opposing depressions may contact or engage each other,but the opposing depressions do not have to touch or engage.

Significantly, the blow-molded table top can be quickly and easilyconstructed. Advantageously, the blow-molding process allows theopposing walls, depressions and other desired features to be quickly andeasily formed in the table top. In addition, the blow-molded table topcan be constructed as an integral, one-piece structure to help create astrong and rigid table top, but the table top could also be constructedfrom two or more pieces that are interconnected.

A further aspect of the table is the table top can be constructed withthin outer walls that decrease the amount of plastic required toconstruct the table top. As discussed above, the opposing walls anddepressions allow a strong and sturdy table top to be constructed. Theseand other features also allow the table top to be constructed withrelatively thin outer walls, which reduces the amount of plasticrequired to construct the table top. This may save manufacturing costsand reduce the amount of resources required to construct the table top.The thin outer walls may also allow the table top to be cooled morequickly during the manufacturing process, which may allow the table topsto be manufactured more quickly and efficiently.

Additionally, because the table top may be constructed from blow-moldedplastic with thin outer walls, this allows a table with reduced weightto be constructed. Significantly, the lightweight table can be easilytransported, which decreases shipping costs. Additionally, the consumermay appreciate the reduced weight because they can much more easily moveand/or assemble the table.

Another aspect of the table is the blow-molded table top may include oneor more features that are integrally formed in the table top as part ofa unitary, one-piece structure. Advantageously, this may reduce thenumber of steps required in the manufacturing process, which may reducethe overall cost of the table. For example, the depressions may beintegrally formed in the table top during the manufacturing process. Inaddition, one or more mounting portions may be integrally formed in thetable top to allow the frame and/or legs to be attached to the tabletop. The mounting portions may also allow the frame and/or legs to beattached to the table top without the use of mechanical fasteners suchas bolts or screws.

Yet another aspect of the table is the one or more depressions formed inthe table top may be located in a predetermined pattern to increase thestrength of the table top and/or decrease the amount of plastic used toconstruct the table top. Advantageously, if the depressions are placednear each other, then the table top may be constructed with thinnerouter surfaces or walls and the strength of the table top may beincreased. Desirably, the locations of the depressions do not varysignificantly even when other features are integrally formed in thetable top. Thus, for example, the depressions are preferably positionedin close proximity and in the same general pattern even around featuressuch as attachment points, edges and other features of the table top. Inaddition, one or more depressions may be formed within the variousfeatures to maintain the generally consistent pattern of depressions.Significantly, the generally uniform pattern of depressions may allow atable top with homogeneous characteristics to be constructed.

A further aspect of the table is the legs can preferably be moved into astorage position to allow the table to be more easily transported orshipped. Desirably, the legs are at least partially disposed withinrecesses or channels to allow the height of the table in the storageposition to be decreased. This may also allow the tables to be moreeasily stacked, shipped and transported. The legs may also have an ovalor other non-circular configuration to further decrease the height ofthe table in the storage position.

Another aspect is the table may be easily assembled and/or disassembledbecause it does not include any heavy or complex mechanisms to attachthe legs to the table top. In contrast, the table preferably includes aframe that can be attached to the table top by a snap, friction orinterference fit. Specifically, the frame preferably includes twoelongated side rails that are connected to frame mounting portions thatare integrally formed in the table top. Significantly, no bolts, screwsor other mechanical fasteners are required to attach the frame to thetable top, but fasteners may be used if desired. Because mechanicalfasteners are not required to attach the frame to the table top, fewerparts are required to assemble the table and no decrease in thestructural integrity or strength of the table is created.

Still another aspect is the table can be manufactured quickly andeasily. In particular, because the frame can be connected to the tabletop by a snap, friction or interference fit, no fasteners are requiredto attach the frame to the table top. This may allow the table to beassembled with less time than conventional tables. In addition, becausethe frame may be simply and easily connected to the table top, fewerworkers may be required to assemble the table. Further, the straightforward design and attachment of the frame to the table top may allowthe table to be shipped either assembled or unassembled, and it mayallow retailers or consumers to assemble the table if desired.

A further aspect of the table is the legs may be attached to the frame.In particular, the side rails of the frame may include openings that aresized and configured to receive a cross member that allows the legs topivot between a use position and a storage position relative to thetable top. The openings preferably have a non-circular configuration andthe cross member also has a non-circular cross-sectional configuration.In particular, the openings and the cross member may have oval,elliptical, oblong or egg-shaped configurations. The openings and crossmember are preferably configured such that when the legs are positionedin the folded or stored position, the cross member is relatively looselyheld within the openings in the frame. On the other hand, when the legsare in the extended or use position, the cross member is held tightlywithin the openings in the frame.

Another aspect of the table is the legs may be held in the folded orstorage position by a retaining member or clip. The clip is preferablyconnected to the table top by a clip receiving portion that isintegrally formed in the underside of the table top. The clip ispreferably held within the clip receiving portion by a snap, friction orinterference fit.

Still another aspect of the table is the legs can be held in the uprightor extended position by a support brace. The support brace preferablyincludes a first end that is connected to the leg and a second end thatis connected to a retaining member or bracket. The support brace ispreferably connected to the leg and the bracket without the use ofmechanical fasteners such as screws or rivets.

A further aspect of the invention is the support brace may include alocking mechanism that secures the support brace and the legs in anextended position. The locking mechanism preferably secures the legs inthe extended position regardless of the position or orientation of thetable. Thus, the legs will not move from the extended position to thecollapsed position even if the table is turned on its side or placedupside-down.

Yet another aspect of the table is the bracket or retaining member ispreferably attached to the table top by a snap, interference or frictionfit. Desirably, the bracket is connected to the table top withoutrequiring the use of any fasteners or adhesives, but fasteners oradhesives could be used if desired.

A further aspect is the table can be constructed without requiring theuse of mechanical fasteners or tools. As discussed above, the frame,legs and retaining members can be secured to the table top withoutrequiring the use of mechanical fasteners. In addition, the legs can beconnected to the frame and the support braces without the use ofmechanical fasteners. Thus, the table can be assembled without usingmechanical fasteners such as screws, bolts, and rivets. Advantageously,this may decrease the cost of the table because fewer components arerequired to assemble the table. In addition, the table can be morequickly and easily assembled because it does not require the use toolsto attach the various components. This may also allow the consumer orpurchaser to more easily assemble the table.

Another aspect is the table top may include a downwardly extending lipand the inner surface of the lip may include a number of serrations,notches, ribs, and/or struts that are sized and configured to increasethe strength, rigidity and/or flexibility of the lip. Advantageously,the uneven inner surfaces of the lip may increase the strength, rigidityand/or flexibility of the table top. In addition, the corners of thetable top may also include one or more serrations, notches, ribs, and/orstruts that are sized and configured to increase the strength, rigidityand/or flexibility of the corners.

A still further aspect of the table is the table top may be constructedfrom two or more pieces. The two or more pieces are preferably pivotallyconnected to allow the table top to fold into a compact position. Forexample, the table top may be constructed from a first piece and asecond piece with one or more interlocking portions and one or moreoverlapping portions. These interlocking and/or overlapping portionsallow the two pieces of the table top to be securely interconnected toform a rigid table top. Significantly, the table top constructed fromtwo or more pieces may allow the table to be more easily transportedand/or stored because, for example, it may be folded in half.

Another aspect is the table may include a table top, a frame connectedto the table top, and a pair of openings with a non-circularconfiguration formed in the frame. The table also includes a leg that ismovable between an extended position and a collapsed position relativeto the table top, and a connecting rod that connects the leg to the pairof openings in the frame. The connecting rod preferably has anon-circular cross-sectional configuration and the connecting rod issized and configured to have one or more gaps between the connecting rodand the openings to allow the connecting rod to move within the openingswhen the leg is in the collapsed position. The connecting rod is alsosized and configured to securely hold the leg in a generally fixedposition within the openings when the leg is in the extended position.For example, the height of the openings in the frame may be generallyequal to the height of the connecting rod and the width of the openingsin the frame may be significantly larger than the width of theconnecting rod. On the other hand, the width of the openings may belarger than the height of the openings and the height of the connectingrod may be larger than the width of the connecting rod.

A further aspect is the table may include a table top, a frame connectedto the table top, a pair of openings formed in the frame, and a legincluding a connecting rod that is inserted into the openings in theframe. The rotation of the connecting rod within the openings may movethe leg between an extended position and a collapsed position.Advantageously, the connecting rod is loosely held within the openingswhen the leg is in the collapsed position and the connecting rod issecurely hold within the openings when the leg is in the extendedposition. The openings in the frame may have a non-circularconfiguration and/or the connecting rod may have a non-circularcross-sectional configuration.

These and other aspects, features and advantages of the presentinvention will become more fully apparent from the following detaileddescription of preferred embodiments and appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is generally directed towards a table with a framethat can be connected to the table top without using mechanicalfasteners. The principles of the present invention, however, are notlimited to tables with frames that can be connected to table topswithout using mechanical fasteners. It will be understood that, in lightof the present disclosure, the table disclosed herein can besuccessfully used in connection with other types of furniture andstructures.

Additionally, to assist in the description of the table, words such astop, bottom, front, rear, right and left are used to describe theaccompanying figures. It will be appreciated, however, that the tablecan be located in a variety of desired positions—including variousangles, sideways and even upside down. A detailed description of thetable now follows.

As shown in FIGS. 1 and 2, the table 10 includes a table top 12 with anupper surface 14, a lower surface 16, a first end 18, a second end 20, afront side 22 and a rear side 24. The upper surface 14 of the table top12 is preferably generally planar to create a smooth, flat workingsurface, but the upper surface could also be textured and have othersuitable configurations depending, for example, upon the intended use ofthe table 10. The table top 12 may also include an edge 26 that isdisposed about the outer perimeter or periphery of the table top. All ora portion of the edge 26 may be beveled, sloped or rounded to, forexample, increase the comfort and safety of the user. The table top 12may also include a downwardly extending lip 28 disposed near or at theouter portion of the table top. The lip 28 preferably extends downwardlybeyond the lower surface 16 of the table top 12 and the lip may bealigned with or form a part of the edge 26 of the table top. It will beappreciated that the lip 28 may also be spaced inwardly from the edge 26of the table top 12. Various embodiments of a lip that may be used inconjunction with the table top 12 are disclosed in Assignee's co-pendingU.S. patent application Ser. No. 10/096,814, entitled Portable FoldingUtility Table with Integral Table Top and Lip, which is herebyincorporated by reference in its entirety.

The table top 12 preferably has a generally rectangular configurationwith rounded corners and slightly rounded edges 26. Desirably, the tabletop 12 has a relatively large size and it is configured for use as abanquet style table. In particular, the table top 12 may have a lengthof about five feet (or about sixty inches) and a width of about two andone-half feet (or about thirty inches), but the table top can be largeror smaller. For example, the table top 12 could be six or eight feet inlength, and the table top could be two or three feet in width. Oneskilled in the art will appreciate that the table top 12 can be largeror smaller according, for example, to the intended use of the table 10.Additionally, the table top 12 may have other suitable shapes andconfigurations such as square, circular, oval, and the like depending,for example, upon the intended use of the table 10. In addition, thecorners and edges 26 of the table top 12 do not have to rounded and, incontrast, the corners and edges could have any desirable configuration,but the rounded features may increase the comfort and/or safety of theuser. Further, the table top 12 could be sized and configured for usewith other types of tables such as utility tables, card tables,personal-sized tables, and the like.

The table top 12 is preferably constructed from a lightweight materialand, more preferably, the table top is constructed from plastic, such ashigh density polyethylene. The plastic table top 12 is desirably formedby a blow-molding process because, for example, it allows a strong,lightweight, rigid and sturdy table top to be quickly and easilymanufactured. Advantageously, the blow-molded plastic table top 12 islighter weight that conventional table tops constructed from wood ormetal. The blow-molded plastic table top 12 is lightweight because it issubstantially hollow. It will be appreciated that the substantiallyhollow table top 12 can include table tops that are generally hollow orcompletely hollow.

The table top 12 is preferably constructed from blow-molded plasticbecause blow-molded plastic table tops are relatively durable, weatherresistant, temperature insensitive, corrosion resistant, rust resistant,and blow-molded plastic generally does not deteriorate over time. Oneskilled in the art, however, will appreciate that the table top 12 doesnot have to be constructed from blow-molded plastic and other suitablematerials and/or processes can be used to construct the table top suchas other types of plastics, polymers and synthetic materials. Inaddition, the table top 12 may be constructed from other materials withsufficient strength and desirable characteristics such as plywood,particle board, solid wood, wood slates, metal alloys, fiberglass,ceramics, graphite, and the like.

The upper surface 14 and the lower surface 16 of the table top 12 arespaced apart a given distance and these two spaced apart surfaces helpcreate a rigid and strong table top 12. Preferably, the upper surface 14and the lower surface 16 are separated by a generally constant distanceso that the surfaces are generally aligned in parallel planes. The upperand lower surfaces 14, 16 of the table top 12 may also be interconnectedby one or more tack-offs, kiss-offs or depressions 30, or otherreinforcement structures, which may be sized and configured to furtherincrease the strength and rigidity of the table top 12. Advantageously,the depressions 30 and/or other reinforcement structures can beintegrally formed as part of a unitary, one-piece table top 12 duringthe blow-molding process.

The depressions 30 are preferably located in the lower surface 16 oftable top 12 and the depressions are preferably sized and configured toincrease the strength and structural integrity of the table top. Thedepressions 30 preferably extend towards the upper surface 14 of thetable top and the ends of the depressions 30 may contact or engage theupper surface of the table top 12, or the ends of the depressions may bespaced from the upper surface of the table top. As shown in FIGS. 2 and3, the depressions 30 preferably cover substantially the entire lowersurface 16 of the table top 12, but it will be appreciated that thedepressions may cover only a portion of the table top. Additionally,while the depressions 30 are shown and described as being located in thelower surface 16 of the table top 12, it will be appreciated that thedepressions could be formed in any desired portion of the table top. Forexample, it will be appreciated that one or more depressions 30 may beformed in the upper surface 14 of the table top 12 and one or moredepressions may be formed in the lower surface 16 of the table top, andthese opposing depressions may be generally aligned. At least a portionof these opposing depressions 30 may contact or engage each other, butthe opposing depressions do not have to touch or engage.

The depressions 30 are preferably arranged into a predetermined patternor array in order to increase the strength and structural integrity ofthe table top 12. In particular, the depressions 30 are preferablyspaced closely together in a predetermined pattern such that thedistance between the depressions is minimized. Advantageously,minimizing the distance between the depressions 30 may minimize theunsupported areas of the upper surface 14 of the table top 12, which mayincrease the smoothness of the upper surface of the table top. Inaddition, minimizing the distance between the depressions 30 mayincrease the structural integrity and strength of the table top 12.Thus, the depressions 30 are desirably closely spaced on the lowersurface 16 of the table top 12 such that the depressions are separatedby a minimum distance in order to create a table top with greaterstrength, structural integrity, and an upper surface 14 with increasedsmoothness.

Advantageously, the increased structural integrity and strength of thetable top 12 may allow the outer wall thickness of the table top to bedecreased, which may allow less plastic to be used to construct thetable 10. Because less plastic may be required to construct the tabletop 12, that may allow the cost of the table 10 to be decreased. Inaddition, the blow-molded table top 12 may cool more quickly during themanufacturing process because of the thinner outer wall. This allows thetable top 12 to be removed from the manufacturing mold more quickly andit may allow the table top to be removed at a higher temperature becauseit dissipates heat much more rapidly. Significantly, because the cycletime required to construct the table top 12 may be decreased, themanufacturing efficiency may be increased.

The depressions 30 are also preferably arranged in a predeterminedpattern with a generally constant and uniform spacing so that the tabletop 12 has generally uniform characteristics. In particular, thedepressions 30 are preferably arranged into a uniform pattern across theentire surface of the table top 12 so that the strength, structuralintegrity and/or other characteristics of the table top are generallyuniform throughout the table top. Thus, the table top 12 has fewer, ifany, weak or unsupported portions which decrease the strength andstructural integrity of the table top. Thus, the depressions 30 may beused to create a table top 12 with generally uniform characteristicsthroughout the table top.

Desirably, other features formed in the table top 12 are sized andconfigured such that they do not significantly disturb or disrupt thedesired pattern of depressions 30. In addition, the depressions 30 arepreferably integrally formed in the table top 12 as part of a unitary,one-piece structure. Advantageously, the depressions 30 can beintegrally formed in the table top 12 during the blow-molding process.Additional details regarding the size, shape and configuration ofdepressions that are suitable for use in connection with the table top12 are disclosed in Assignee's co-pending U.S. patent application Ser.No. 10/409,000, filed Apr. 8, 2003, entitled High-Strength, LightweightBlow-molded Plastic Structures, which is hereby incorporated byreference in its entirety.

As best seen in FIGS. 3, 3A and 4, a frame 32 is connected to the lowersurface 16 of the table top 12. The frame 32 desirably includes two siderails 34 that extend along the length of the table top 12 and the siderails are preferably positioned near opposing edges 26 of the table top.In particular, the side rails 34 are preferably disposed inwardly fromthe lip 28 such that there is a gap or space between the side rails andthe lip. The side rails 34 preferably extend almost the entire length ofthe table top 12 to provide increased strength and rigidity for thetable top, but the side rails may extend along only a portion of thelength of the table and the side rails may not be required to provideincreased strength or rigidity to the table top.

The frame 32 is desirably constructed from metal, which may easily beformed into the desired configuration by known operations such asstamping and bending, and the metal may be coated or painted as desired.The frame 32 may also include one or more end rails attached to the endsof the side rails 34 and the frame may provide attachment points for thelegs, as discussed in more detail below. While the frame 32 preferablyincludes two side rails 34 that are generally aligned in a parallelconfiguration, it will be appreciated that the frame may have othersuitable configurations and arrangements depending, for example, uponthe size and shape of the table top 12 or the intended use of the table10.

The frame 32 is desirably connected to the lower surface 16 of the tabletop 12 by one or more frame mounting portions 36 that allow the frame tobe connected to the table top by a snap, friction or interference fit.Advantageously, the connection of the frame 32 to the table top 12 doesnot require the use of mechanical fasteners such as bolts or screws,which desirably expedites the manufacturing or assembly process, butfasteners may be used if desired. Additionally, because screws, boltsand other types of mechanical fasteners are not required to attach theframe 32 to the table top 12, no holes or other types of stressconcentrations are formed in the table top. Thus, the strength andstructural integrity of the table top 12 is not compromised by drillingholes in the table top. In addition, because the frame 32 is preferablynot bonded to the lower surface 16 of table top 12, the table top is notweakened or damaged by adhesive. Thus, strength and integrity of thetable top 12 may be retained because the frame 32 is not screwed, boltedor bonded directly to lower surface 16 of the table top. Further, theattachment of the frame 32 to the frame mounting portions 36 may reducethe likelihood of deformation or damage to the table top. Finally, theconnection of the frame 32 to the table top 12 without using mechanicalfasteners or adhesive may facilitate assembly of the table 10 by theretailer or consumer.

The frame mounting portions 36 are sized and configured to retain theframe 32 in a generally fixed position and to prevent the unintendedremoval of the frame from the table top 12. The frame mounting portions36 desirably have about the same length as the side rails 34 and thisallows the frame 32 to be connected to the frame mounting portions alongthe entire length of the side rails. Advantageously, any forces actingon the table top and/or the frame 32 are distributed over a large area.In contrast, conventional tables that attached the frame to the tabletop by mechanical fasteners distributed forces over a much smaller area,which makes conventional tables much more likely to fail. Therefore, theframe mounting portions 36 may provide a very secure attachment of theframe 32 to the table top 12 even though mechanical fasteners are notrequired. It will be appreciated that the frame mounting portions 36 mayhave a length less than the frame 32 so that only portions of the frameare attached to the frame mounting portions.

As best seen in FIGS. 3A and 4, the side rails 34 of the frame 32preferably have a generally U-shaped configuration with a first side 38,a second side 40, and a connecting portion 42. The first side 38 of theside rail 34 includes an engaging portion 44 and the second side 40includes an engaging portion 46. The engaging portions 44, 46 are spacedapart a distance and the engaging portions are sized and configured tosecurely attach the side rails 34 of the frame 32 to frame mountingportions 36. Because the frame mounting portions 36 are desirablyintegrally formed in the table top 12 as part of a unitary, one-piecestructure, the frame 32 can be directly attached to the table top 12.

As shown in FIG. 3A, the frame mounting portion 36 includes an opening48 and a recess 50 that is sized and configured to receive a portion ofthe side rails 34. In particular, the opening 48 to the frame mountingportion 36 is preferably slightly smaller than the distance separatingthe engaging portions 44, 46 of the side rails 34. Thus, when theengaging portions 44, 46 of the side rails 34 are inserted into theopening 48, the engaging portions 44, 46 must deflect inwardly and/orthe opening must deform to allow the side rails to be inserted into therecess 50 of the frame mounting portion 36. Once the engaging portions44, 46 are inserted into the recess 50, the engaging portions and/or theopening 48 resiliently or elastically return to there respectiveoriginal positions to secure the side rail 34 within the frame mountingportion 36.

The engaging portions 44, 46 of the side rails 34 may engage one or morecorresponding surfaces within the recess 50 to help secure the frame 32to the table top 12. As seen in FIGS. 3A and 4, the engaging portions44, 46 are preferably the ends of the first side 38 and second side 40of the side rail 34 that are bent outwardly at an angle less than about90° relative to the first and second sides, respectively. The engagingportions 44, 46 preferably include sharp edges 52 that are sized andconfigured to engage corresponding side walls 54, 56 of the recess 50.Advantageously, the sharp edges 52 engage and bite into the softer,blow-molded plastic material of the recess 50 to allow the frame 32 tobe securely connected to the table top 12. Significantly, the engagementof the engaging portions 44, 46 and the edges 52 to the recess 50provides a large contact area between the frame 32 and the framemounting portions 36.

As seen in FIGS. 2, 3 and 3A, the frame mounting portions 36 are formedin the lower surface 16 of the table top 12 and one or more depressions30 are preferably formed in the lower portion of the recess 50 so that agenerally consistent, uniform pattern of depressions is formed in thetable top 12. Advantageously, this helps create a table top 12 withincreased strength, structural integrity and generally uniformcharacteristics. One skilled in the art will appreciate that thedepressions 30 could have other suitable arrangements and depressions donot have to be formed in the lower portion of the recess 50.

In addition, because at least a portion of the side rails 34 areinserted into the recesses 50, the side rails and the connecting portion42 of the frame 32 do not extend a large distance away from the lowersurface 16 of the table top 12. This may allow a table 10 with a lowprofile to be designed and manufactured. Significantly, if the height ofthe table top 12 is relatively small, then the tables 10 may be moreeasily stacked. This may assist in the shipping and storage of thetables 10. Additionally, the lip 28 may have a height that is largerthan or equal to the distance that the side rails 34 extend from thelower surface 16 of the table top 12 so that the frame is generallyhidden from view when the table 10 is viewed from a plane generallyaligned with the upper surface 14 of the table top 12. Advantageously,because the frame 32 may be completely or generally hidden from view,the frame does not have to be finished and it may contain visibleimperfections or flaws. In addition, because the frame 32 may becompletely or generally hidden from view by the lip 28, a moreaesthetically pleasing table 10 may be created. It will be appreciated,however, that the lip 28 does not have to hide all or a portion of theframe 32 from view.

As shown in the accompanying figures, the frame 32 engages or abutsseveral different surfaces of the frame mounting portions 36 to securelyattach the frame to the table top 12. The engagement of the side rails34 to several different surfaces of the frame mounting portions 36 overan extended length allows any forces or loads on the table top 12 andthe frame 32 to be distributed over a large area, which helps preventfailure of the table 10. Additionally, because the engaging portions 44,46 of the side rails 34 preferably extend outwardly and are spaced widerapart than the opening 48 to the frame mounting portions 36, a securesnap, friction or interference connection of the frame 32 to the tabletop 12 may be established. Further, the side rails 34 and the framemounting portions 36 are preferably generally symmetrical to helpprevent undesirable twisting of the frame 32 and/or table top 12.

Advantageously, the frame 32 can be quickly and easily connected to thetable top 12 by inserting the engaging portions 44, 46 of the side rails34 into the openings 48 in the frame mounting portions 36. As discussedabove, mechanical fasteners such as screws or bolts are not required toconnect the frame 32 to the table top 12, but such fasteners may be usedif desired. In addition, the frame 32 can be more easily disconnectedfrom the table top 12, if desired, because mechanical fasteners do nothave to be removed. Other suitable embodiments for connecting a frame toa table top are disclosed in Assignee's co-pending U.S. patentapplication Ser. No. 10/409,259, filed Apr. 8, 2003, entitled Frame ThatCan Be Attached to a Table Top without Mechanical Fasteners, which ishereby incorporated by reference in its entirety.

As best seen in FIGS. 4, 6 and 7, the side rails 34 of the frame 32include openings 60 that are sized and configured to allow legs 62, 64to be attached to the table 10. The legs 62, 64 are sized and configuredto support the table top 12 above a surface such as a floor and the legsmay be adjustable in length. The legs 62, 64 are preferably disposedbetween the side rails 34 of the frame and the openings 60 arepreferably located near the ends of the side rails 34 in generallyaligned pairs. It will be appreciated that the openings 60 could bepositioned in any desired locations depending, for example, theconfiguration of the legs 62, 64 and/or the frame 32.

The openings 60 preferably have a non-circular configuration such asoval, oblong, egg-shaped, kidney-shaped, key-shaped, etc., which issized and configured to receive a portion of the legs 62, 64. As shownin the accompanying figures, the openings 60 include a length 66 that isgenerally aligned with the longitudinal length of the side rails 34 anda height 68 that is generally aligned with the height of the side rails.It will be appreciated that one or more bushings, sleeves, bearings, andthe like may be used in conjunction with openings 60 to facilitate theconnection of the legs 62, 64 to the frame.

The legs 62, 64, which are movable between a first extended position inwhich the legs extend away from the table top 12 and a second collapsedposition in which the legs are positioned near the table top forstorage, include a connecting rod 70 that is sized and configured to beinserted into the openings 60 in the side rails 34 of the frame 32. Therotation of the connecting rod 70 within the opening 60 allows the legs62, 64 to move between the first and second positions relative to thetable top 12.

As best seen in FIGS. 2 and 3, the lower surface 16 of the table top 12includes receiving channels 72 that are sized and configured to receiveat least a portion of the legs 62, 64 in the collapsed position. Thereceiving channels 72 advantageously receive at least a portion of thelegs 62, 64 to decrease the height of the table 10 in the storageposition. This allows more tables 10 to be stacked and stored in alimited amount of space, and this may facilitate shipping andtransportation of the tables. As shown in the accompanying figures, oneor more depressions 30 are preferably located in the receiving channels72 so that the consistent pattern and arrangement of depressions ismaintained. It will be appreciated, however, that depressions 30 do nothave to be formed in the receiving channels 72 and receiving channels donot have to be formed in the table top 12.

The connecting rod 70 preferably has a non-circular cross-sectionalconfiguration and the openings 60 in the side rails 34 of the frame 32also preferably have a non-circular configuration. For example, theopenings 60 and the connecting rod 70 may have a configuration that isoval, oblong, egg-shaped, kidney-shaped, key-shaped, etc. Desirably, thenon-circular opening 60 and the non-circular cross-sectionalconfiguration of the connecting rod 70 are sized and configured suchthat the connecting rod is not securely held within the opening when thelegs are in the collapsed position. Thus, in the collapsed position, oneor more small gaps or spaces are located between connecting rod 70 andthe opening 60 so that the connecting rod can move slightly within theopening. Advantageously, this allows the legs 62, 64 to be more easilyconnected to the side rails 34 because of the larger clearance.

Additionally, because there is some movement or “play” between the legs62, 64 and the side rails 34 when the legs are in the collapsedposition, that may allow the legs to fold flatter such that the legscontact and/or are generally parallel to the lower surface 16 of thetable top 12. Further, the movement of the legs 62, 64 within theopenings 60 may allow the legs to be positioned in the desired collapsedposition even if, for example, there is some slight imperfection in thetable 10 or if a portion of the table has expanded or contracted due totemperature. Accordingly, the tables 10 may be more easily manufacturedand assembled because of the greater tolerances, and the tables may foldflatter to facilitate stacking of the tables.

When the legs 62, 64 are in the extended position, however, theconnecting rod 70 is preferably securely held within the openings 60 torigidly and securely attach the legs to the table top 12. In particular,when the connecting rod 70 is rotated within the openings 60 to theextended position, the connecting rod and openings are sized andconfigured such that there is no or very little movement or play betweenthe connecting rod and the openings. Thus, the legs 62, 64 desirably donot shake or wobble in the extended position.

For example, the openings 60 in the side rail 34 may have a height ofabout 0.94 ( 15/16) inches and an overall length of about 1.5 inches,and the connecting rod 70 may have an oval configuration with a heightof about 0.94 ( 15/16) inches and a width of about 0.75 (¾) inches.Advantageously, these sizes and configurations allow the connecting rod70 to be relatively easily inserted into the openings 60 and theconnecting rod can move slightly within the opening when the legs 62, 64are in the collapsed position. In particular, as best seen in FIG. 6,the connecting rod 70 can move within the opening 60 because there aregaps or spaces between the connecting rod and the opening. On the otherhand, when the legs 62, 64 are in the extended position, the connectingrod 70 is securely held within the opening 60. As best seen in FIG. 7,the upper and lower ends of the connecting rod 70 engage the upper andlower portions of the opening 60 when the legs 62, 64 are in theextended position.

It will be appreciated that the openings 60 and connecting rod 70 canhave other suitable sizes and configurations depending, for example,upon the size and/or intended use of the table 10. It will also beappreciated that other suitable combinations of the openings 60 andconnecting rod 70 may be utilized, such as the combination of generallycircular openings and non-circular connecting rods, or non-circularopenings and generally circular connecting rods. Further, it will beappreciated that the legs 62, 64 may be attached to the frame 32 ortable top 12 by other suitable types of devices and mechanisms.

The legs 62, 64, as best seen in FIGS. 4 and 5, are attached to orinclude the connecting rod 70 and the legs include a pair of elongatedsupport members 74, 76 and a foot portion 78. Advantageously, the twoseparate elongated support members 74, 76 may help prevent twisting ortorque on the connection of the support members to the connecting rod 70and the foot portion 78. Additionally, while the elongated supportmembers 74, 76 are preferably welded to the connecting rod 70 and thefoot portion 78, the support members may be connected to the connectingrod and foot portion by any suitable method or device.

As best seen in FIG. 5, the elongated support members 74, 76 preferablyhave a generally curved configuration. In particular, the upper portionsof the elongated support members 74, 76 are preferably spaced apart toprovide a secure attachment of the support members to the connecting rod70, the middle portions of the elongated support members are preferablymore closely spaced together, and the lower portions of the elongatedsupport members are spaced apart to provide a secure connection to thefoot portion 78. The foot portion 78 preferably has an upwardlyextending curved section and feet 82 may be connected to the ends of thefoot portion. A connecting member 80 is preferably disposed near themiddle portion of the elongated support members 74, 76 to help maintainthe support members in the desired positions.

The connecting rod 70, elongated support members 74, 76 and foot portion78 of the legs 62, 64 are desirably constructed from hollow metal tubesbecause the metal tubes are relatively lightweight and strong. Thehollow metal tubes forming the connecting rod 70, elongated supportmembers 74, 76 and foot portion 78 desirably have a generally ovalconfiguration to provide increased strength. Advantageously, the ovalconfiguration may also be used to create a thinner profile for the legs62, 64, which may create a thinner profile for the table 10 when thelegs are in the collapsed position.

It will be appreciated that the legs 62, 64 may be constructed fromother materials with the suitable characteristics and the legs may haveother shapes and configurations depending, for example, upon theintended use of the table 10. For example, the legs 62, 64 may includeonly a single elongated support member or multiple elongated supportmembers, and the legs may be constructed as a single component ormultiple components that are connected together. It will further beappreciated that the legs 62, 64 need not be in pivotal engagement withframe 32 or the table top 12 to be collapsible. For example, the legs62, 64 may be detachably connected to the table top 12 such that when itis desired to collapse the table 10 for storage, the legs are detachedfrom the table top.

A support brace 84 is used to support the legs 62, 64 in the extendedposition. The support brace 84 includes a first end 86 that is attachedto the leg 62, 64 and a second end 88 that is attached to the table top12 by a mounting member or bracket 90. The support brace 84 ispreferably pivotally connected to the leg 62, 64 and the bracket 90 toallow the leg to be moved between the extended and collapsed positions.It will be appreciated that while the legs 62, 64 are in the extended orcollapsed positions, the support brace 84 is also in a correspondingextended or collapsed position. Advantageously, the support brace 84 canbe connected to the leg 62, 64 and the bracket 90 without the use ofmechanical fasteners such as screws, rivets or bolts. Significantly, thetable 10 may be built more quickly because fewer components may berequired to assemble the table and no mechanical fasteners are needed toattach the support brace 84 to the legs 62, 64 or the table top 12. Itwill be appreciated, however, that one or more mechanical fasteners maybe used to connect the support brace 84 to the leg 62, 64 and/or thetable top 12.

In greater detail, as best seen in FIGS. 10, 11 and 12, the first end 86of the support brace 84 includes two curved arms 92 and each curved armhas an opening 94 that leads to a generally circular interior portion96. The two generally circular interior portions 96 are generallyaligned along the same axis and disposed at the end 86 of the supportbrace 84. The generally circular interior portions 96 are sized andconfigured to receive corresponding receiving portions 98 formed in theconnecting member 80. In particular, the receiving portions 98 include aflange 100 with rounded ends 102 and corresponding openings 104. Thesupport brace 84 is connected to the leg 62, 64 by disposing the roundedends 102 of the flange 100 within the generally circular interiorportions 96 of the curved arms 92. In addition, the curved arms 92 ofthe support brace 84 are disposed within the openings 104 in theconnecting member 80. Advantageously, when the support brace 84 isconnected to the legs 62, 64 and the table top 12, the support bracecannot be inadvertently disconnected from the legs. While thisconnection of the support brace 84 to the leg 62, 64 does not requirethat use of any mechanical fasteners, it will be appreciated thatmechanical fasteners may be used to connect the support brace to thelegs 62, 64.

In order to attach the support brace 84 to the leg 62, 64, the twogenerally circular interior portions 96 of the curved arms 92 arecoaxially aligned with the rounded ends 102 of the flange 100. Therounded ends 102 of the flange 100 are then inserted into the generallycircular interior portions 96 of the support brace 84 and the arms 92are inserted into the openings 104 in the flange. Significantly, whenthe second end 88 of the support brace 84 is attached to the table top12, the first end 86 of the support brace cannot be disconnected fromthe leg 62, 64. This helps create a strong and secure table 10 becausethe support brace 84 cannot be unintentionally disconnected from leg 62,64 when the table is assembled. However, when the second end 88 of thesupport brace 84 is disconnected from the table 10, then the first end86 of the support brace can be disconnected from the leg 62, 64. Thisallows the table 10 to be quickly and easily assembled, and it allowsthe table to be quickly and easily disassembled.

The brackets 90, as best seen in FIGS. 3 and 3B, are connected to thelower surface 16 of the table top 12 by bracket mounting portions 110that allow the brackets to be connected to the table top by a snap,friction or interference fit. Advantageously, the connection of thebrackets 90 to the table top 12 does not require the use of mechanicalfasteners such as bolts or screws, which desirably expedites themanufacturing or assembly process, but fasteners may be used if desired.Additionally, because screws, bolts or other types of mechanicalfasteners are not required to attach the brackets 90 to the table top12, no holes or other types of stress concentrations are formed in thetable top. Thus, the strength and structural integrity of the table top12 is not diminished by drilling or forming holes in the table top. Inaddition, because the brackets 90 are preferably not glued to the lowersurface 16 of table top 12, the table top is not weakened or damaged byadhesive. Thus, strength and integrity of the table top 12 may beretained because the brackets 90 are not screwed, bolted or bonded tobottom surface 16 of the table top. Further, the connection of thebrackets 90 to the table top 12 without using mechanical fasteners oradhesives may facilitate assembly of the table 10 by the retailer orconsumer.

The bracket mounting portions 110 are sized and configured to retain thebrackets 90 in generally fixed positions and to prevent the unintendedremoval of the brackets from the table top 12. Advantageously, thebrackets 90 engage a relatively large portion of the table top 12 sothat forces applied to the brackets are distributed over a large area.This provides an improved and more secure connection of the brackets 90to the table top 12 because forces are distributed over a much largerarea than brackets attached to a table top only by mechanical fasteners.Additionally, the connection of the brackets 90 to the table top 12 bythe bracket mounting portions 110 may be less likely to fail thanconventional brackets attached to a table top by mechanical fastenersbecause of the larger engagement area.

As best seen in FIG. 3B, the bracket 90 includes a main body portion 112with a first end 114 and a second end 116. The first end 114 of thebracket 90 includes an engaging portion 118 with a rounded flange 120and an edge 122. The second end 116 of the bracket 90 includes aretaining portion 124 with a first angled portion 126 and a secondangled portion 128. The first angled portion 126 is preferably disposedat an angle less than about 90° with respect to the main body portion112 of the bracket 90 so that it is angled towards the first end 114 ofthe bracket 90. As discussed below, the engaging portion 118 and theretaining portion 124 are sized and configured to securely attach thebracket 90 to bracket mounting portion 110 by a snap, friction orinterference fit. Additionally, the bracket 90 is preferably directlyattached to the table top 12 because the bracket mounting portions 110are desirably integrally formed in the table top as part of a unitary,one-piece structure. It will be appreciated, however, that the bracket90 does not have to be directly attached to the table top 12 and thebracket does not have to be attached to the table top by the bracketmounting portions 110.

As shown in FIG. 3B, the bracket mounting portion 110 includes a firstrecess 130 and a second recess 132 that are sized and configured toreceive the first end 114 and the second end 116 of the bracket 90,respectively. In particular, the first recess 130 is disposed towardsthe middle of the table top 12 and the first recess preferably has alength that is approximately the same as the length of the first end 114of the bracket 90. A protrusion or lip 134 projects into an upperportion of the first recess 130 and it is sized and configured to fitwithin the inner portion of the rounded flange 120 on the first end 114of the bracket 90. The second recess 132 is disposed towards the end ofthe table top 12 and it has a length that is approximately the same asthe length of the second end 116 of the bracket 90. A protrusion or lip136 extends into an upper portion of the second recess 132 and it issized and configured to contact or abut at least a portion of the firstdownwardly extending portion 126 on the second end 116 of the bracket90. The distance from the first edge 122 on the first end 114 of thebracket 90 to the innermost part of the first downwardly extendingportion 126 on the second end 116 of the bracket is preferably smallerthan the distance from the protrusion 134 extending into the firstrecess 130 to the protrusion 136 extending into the second recess 132 ofthe bracket mounting portion 110, which allows the bracket to beconnected to the bracket mounting portion 110 by a snap, friction orinterference fit.

In order to connect the bracket 90 to the table top 12, the engagingportion 118 on the first end 114 of the bracket is inserted into thefirst recess 130 of the bracket mounting portion 110 such that therounded flange 120 and the edge 122 engage a portion of the table top12. In particular, the edge 122 preferably engages a portion of thefirst recess 130 and/or the protrusion 134 and the rounded flange 120contacts or abuts at least a portion of the protrusion. The second end116 of the bracket 90 is then inserted into the second recess 132 of thebracket mounting portion 110. As the retaining portion 124 on the secondend 116 of the bracket 90 is inserted into the second recess 132, thefirst angled portion 126 and/or the protrusion 136 deflects or deformsto allow the second end of the bracket to be inserted into the recess.Once the second end 116 of the bracket 90 is inserted into the secondrecess 132, the first angled portion 126 and/or the protrusion 136resiliently or elastically returns to there original positions to securethe second end of the bracket in a fixed position. Accordingly, thebracket 90 is preferably connected to the bracket mounting portion 110of the table top 12 by a snap, friction or interference fit, and thisallows the bracket to be securely connected to the table top without theuse of fasteners. It will be appreciated, however, that fasteners oradhesives could also be used to secure the bracket 90 to the table top12 if desired.

The rounded flange 120 on the first end 114 of the bracket 90 preferablyhas a radius of curvature that generally corresponds to the radius ofcurvature of the protrusion 134 to help secure the bracket 90 to thebracket mounting portion 110. Similarly, the first angled portion 126 onthe second end 116 of the bracket 90 preferably has a radius ofcurvature that generally corresponds to the radius of curvature of theprotrusion 136. This provides a large contact area between the bracket90 and the bracket mounting portion 110. Additionally, the edge 122 onthe first end 114 of the bracket 90 is preferably sharp so that itengages and bites into the softer, blow-molded plastic material of thetable top 12 to allow the bracket 90 to be securely connected to thetable top. Significantly, the engagement of the first end 114 and thesecond end 116 of the bracket 90 to the first recess 130 and the secondrecess 132 of the bracket mounting member 110, respectively, provides alarge contact area that allows forces or loads on bracket to bedistributed over a large area, which helps provide a secure and durableconnection of the support brace 84 to the table top 12.

As seen in FIG. 2, the bracket mounting portions 110 are formed in thelower surface 16 of the table top 12 and one or more depressions 30 maybe formed in the bracket mounting portions so that a generallyconsistent, uniform pattern of depressions is formed in the table top12. Significantly, all or only a portion of the depressions 30 may beformed in the bracket mounting portions 110 in order to maintain thegenerally uniform pattern of depressions. Advantageously, the uniformpattern of depressions 30 may help create a table top 12 with increasedstrength, structural integrity and generally uniform characteristics.One skilled in the art will appreciate that the depressions 30 couldhave other suitable arrangements and depressions do not have to beformed in the bracket mounting portions 110.

As discussed above, the second end 88 of the support brace 84 isconnected to the bracket 90. As best seen in FIGS. 4 and 14, the secondend 88 of the support brace includes two curved arms 93 and each curvedarm has an opening 95 that leads to a generally circular interiorportion 97. The two generally circular interior portions 97 aregenerally aligned along the same axis and disposed near the end of thesupport brace 84. The generally circular interior portions 97 are sizedand configured to be connected to the second end 116 of the bracket 90.In particular, the generally circular interior portions 97 are sized andconfigured to receive a portion of the first angled portion 126 and thesecond angled portion 128 of the bracket 90. In addition, the curvedarms 93 of the support brace 84 are configured to be disposed withinopenings 99 in the second end 116 of the bracket 90. Advantageously,when the support brace 84 is connected to the legs 62, 64 and the tabletop 12, the support brace cannot be inadvertently disconnected from thebracket 90. While this connection of the support brace 84 to the bracket90 does not require that use of any mechanical fasteners, it will beappreciated that mechanical fasteners may be used to connect the supportbrace to the bracket.

In order to attach the support brace 84 to the bracket 90, the twogenerally circular interior portions 97 of the curved arms 93 arecoaxially aligned with the first angled portion 126 and the secondangled portion 128 on the second end 116 of the bracket. The firstangled portion 126 and the second angled portion 128 are then insertedinto the generally circular interior portions 97 of the support brace 84and the curved arms 93 are inserted into the openings 99 in the secondend 116 of the bracket 90. Significantly, when the support brace 84 isconnected to the bracket 90 and the bracket is connected to the tabletop 12, the support brace cannot be disconnected from the bracket. Thishelps create a strong and secure table 10 because the support brace 84cannot be unintentionally disconnected from bracket 90 when the table isassembled. However, when the bracket 90 is disconnected from the tabletop 12, then the second end 88 of the support brace 84 can bedisconnected from the bracket. This allows the table 10 to be quicklyand easily assembled and disassembled.

As discussed above, the first end 86 of the support brace 84 may bepivotally connected to the legs 62, 64 and the second end 88 of thesupport brace may be pivotally connected to the bracket 90. One skilledin the art, however, will appreciate that the ends 86, 88 of the supportbrace 84 do not have to be pivotally connected to the legs 62, 64 or thebracket 90. Other suitable embodiments for connecting the support braceto the legs and/or the table top are disclosed in Assignee's co-pendingU.S. patent application Ser. No. 10/409,469, filed Apr. 8, 2003, nowU.S. Pat. No. 6,901,867, entitled Pivotal Connection of a Support Braceto a Table Leg and a Table Top, which is hereby incorporated byreference in its entirety.

As best seen in FIGS. 7–10, the support brace 84 includes a first arm140 that is pivotally connected to a second arm 142 by a pin 144. Thepivotal connection of the first and second arms 140, 142 allows thesupport brace 84 to move between the extended position and the collapsedposition. When the support brace 84 is in the collapsed position, thelegs 62, 64 are also in the collapsed position. Similarly, when thesupport brace 84 is in the extended position, the legs 62, 64 are alsoin the extended position. While the support brace 84 preferably pivotsto allow the legs 62, 64 to be moved between the extended position andthe collapsed position, it will be understood that the support bracedoes not require the pivotal connection of the first arm 140 and thesecond arm 142, and the support brace 84 could have other suitablearrangements and/or configurations.

A locking mechanism 146 is preferably used to secure the support brace84 in the extended position, which consequently also secures the legs62, 64 in the extended position. Advantageously, the locking mechanism146 can secure the legs 62, 64 in the extended position regardless ofthe position or orientation of the table 10. Thus, the legs 62, 64 willnot move from the extended position to the collapsed position even ifthe table 10 is turned on its side or upside-down. In addition, thelocking mechanism 146 is preferably biased to remain in the lockedposition and the locking mechanism positively locks the support brace 84and the legs 62, 64 in the extended position. Further, the lockingmechanism 140 preferably requires the user to intentionally unlock themechanism to allow the support brace 84 and the legs 62, 64 to move intothe collapsed position. Thus, the support brace 84 and the legs 62, 64can be positively held in the extended position by the locking mechanism146.

As seen in FIGS. 8–10, the locking mechanism 146 includes an elongatedbody 148 that is generally sized and configured to fit within the secondarm 142 of the support brace 84. In particular, the second arm 142 ofthe support brace 84 has a generally U-shaped configuration with twoopposing sidewalls 150, 152 and the elongated body 148 of the lockingmechanism 146 is generally disposed between the sidewalls and towardsthe end of the second arm nearest the first arm 140. The elongated body148 of the locking mechanism 146 includes a first end 154 that is sizedand configured to engage the pin 144 and a second end 156 with anelongated extension 158. Two outwardly extending tabs or flanges 160,162 are disposed between the ends 154, 156 of the locking mechanism 146and the tabs extend through an opening 164 in the second arm 142 of thesupport brace 84. The elongated extension 158 on the second end 156 ofthe locking mechanism 146 extends through an opening 166 in a flange 168extending from the second arm 142 of the support brace 84. A biasingmember such as a spring 170 is disposed about the elongated extension158 and the biasing member is positioned between the flange 168 and theelongated body 148 of the locking mechanism 146.

The locking mechanism 146 is movable relative to the second arm 142between a locked position in which the elongated body 148 is disposedproximate the end of the second arm nearest the first arm 140, and anunlocked position in which the elongated body is disposed inwardly fromthe end of the second arm and away from the first arm. The spring 170 isdesirably sized and configured to bias the locking mechanism 146 intothe locked position. In this locked position, the first end 154 of theelongated body 148 contacts the pin 144 and the outwardly extending tabs160, 162 are disposed towards the end of the second arm 142 of thesupport brace 84. In the unlocked position, the first end 154 of theelongated body 148 is spaced apart from the pin 144 and the outwardlyextending tabs 160, 162 are spaced away from the end of the second arm142 of the support brace 84. One skilled in the art will appreciate thatother suitable types of biasing mechanisms may be used to bias thelocking mechanism 146 into the locked position.

The first and second arms 140, 142 of the support brace 84 are generallyaligned and at least a portion of the arms overlap when the supportbrace is in the extended position. In particular, as best seen in FIGS.8 and 9, the first arm 140 of the support brace 84 includes twoextensions 172, 174 and the extensions are generally parallel to andoverlap portions of the sidewalls 150, 152 of the second arm 142 whenthe support brace is in the extended position. When the lockingmechanism 146 is in the locked position, the locking mechanism maintainsthe extensions 172, 174 in the generally parallel and overlappingposition with the sidewalls 150, 152 of the second arm 142.Specifically, the outwardly extending tabs 160, 162 engage theextensions 172, 174 to prevent the first arm 140 from moving relative tothe second arm 142. Thus, the outwardly extending tabs 160, 162 preventthe first arm 140 from pivoting relative to the second arm 142, and thatmaintains the support brace 84 and the legs 62, 64 in the extendedposition.

On the other hand, when the support brace 84 is in the collapsedposition, the extensions 172, 174 do not overlap portions of thesidewalls 150, 152 of the second arm 142 of the support brace 84. Incontrast, as best seen in FIG. 6, the extensions 172, 174 are spacedaway from the second arm 142 of the support brace 84 and at least aportion of the second arm may be disposed inside the body of the firstarm 140 to form a small, compact arrangement. Advantageously, thesupport brace 84 does not significantly protrude from the lower surface16 of the table top 12 in the collapsed position. This allows a table 10with a relatively small height when the legs 62, 64 are in the collapsedposition to be constructed, if desired.

When the locking mechanism 146 is in the unlocked position, the lockingmechanism does not secure the support brace 84 in the extended position.In contrast, the locking mechanism 146 allows the first and second arms140, 142 of the support brace 84 to freely move with respect to eachother. In particular, as shown in FIG. 10, when the user moves thelocking mechanism 146 into the unlocked position, the outwardlyextending tabs 160, 162 no longer engage the extensions 172, 174 andthat allows the first and second arms 140, 142 of the support brace 84to freely rotate. Desirably, when the user releases the lockingmechanism 146, the spring 170 causes the locking member to return to itslocked position.

As best seen in FIGS. 6, 9 and 10, the extensions 172, 174 have a curvedfront surface 176 and a generally straight rear surface 178 topositively secure the locking mechanism 146 in the locked position, andto allow the support brace 84 to be moved from the collapsed position tothe extended position without the user unlocking the locking mechanism146. In particular, the curved front surfaces 176 of the extensions 172,174 are sized and configured to engage the outwardly extending tabs 160,162 of the locking mechanism 146 when the support brace 84 is moved fromthe collapsed position to the extended position. Specifically, thecurved front surfaces 176 engage the outwardly extending tabs 160, 162and push the locking member 146 into the unlocked position. When thesupport brace 84 is in the extended position and the first and secondarms 140, 142 are generally aligned, the curved front surface3 176 ofthe extensions 172, 174 no longer engage the tabs 160, 162 and thespring 170 returns the locking mechanism 146 to the locked position.Thus, the locking member 146 allows the support brace 84 to be movedfrom the collapsed position to the extended position without requiringthe user to unlock the locking mechanism.

The generally straight rear surfaces 178 of the extensions 172, 174prevent the locking mechanism 146 from being inadvertently unlocked andallowing the support brace 84 to move from the extended position to thecollapsed position. In particular, the generally straight rear surfaces178 of the extensions 172, 174 engage the generally planar lowersurfaces of the tabs 160, 162, and this engagement of the extensions andtabs prevents the support brace 84 from moving from the extendedposition to the collapsed position. In order to allow the support brace84 to move from the extended position to the collapsed position, theuser must intentionally unlock the locking mechanism 146, and thisallows the support brace and the legs 62, 64 to be collapsed.

Significantly, the locking mechanism 146 is lightweight and includes fewmoving parts. In particular, the locking mechanism 146 is preferablyconstructed from metal and it can be stamped or formed into the desiredconfiguration. Additionally, the second arm 140 is preferablyconstructed from metal and the opening 164, opening 166 and flange 168can be stamped or formed into the desired configuration. While the firstarm 140, second arm 142 and the locking mechanism 146 are preferablyunitary components, it will be appreciated that these components may beconstructed from multiple parts that are connected together. Further,these components may have other suitable configurations and arrangementsdepending, for example, upon the size and/or intended use of the table10.

In operation of the locking mechanism 146, when the second arm 142 is inthe collapsed position and being rotated into the extended position, thecurved front surfaces 176 of the extensions 172, 174 engage theoutwardly extending tabs 160, 162. The rotation of the second arm 142relative to the first arm 140 causes the extensions 172, 174 to push theoutwardly extending tabs 160, 162 and the locking member 146 into theunlocked position. When the support brace 84 is in the extendedposition, the extensions 172, 174 no longer engage the outwardlyextending tabs 160, 162 and the spring 170 forces the locking member 146into the locked position. Alternatively, instead of the extensions 172,174 moving the locking mechanism 146 into the unlocked position whilethe support brace 84 is being moved from the collapsed position to theextended position, the user may manually move the locking mechanism intothe unlocked position. In order to move the support brace 84 and legs62, 64 from the extended position to the collapsed position, the userslides the locking mechanism 146 into the unlocked position, as shown inFIG. 10, which allows the second arm 142 to rotate relative to the firstarm 140. Once the arms 140, 142 are not longer in the extended position,the user can release the locking mechanism 146 and position the legs 62,64 in the collapsed position. Other suitable types of locking mechanismsfor retaining table legs in an extended position are disclosed inAssignee's co-pending U.S. patent application Ser. No. 10/408,949, filedApr. 8, 2003, now U.S. Pat. No. 6,971,321, entitled Table Leg LockingMechanism, which is hereby incorporated by reference in its entirety.

As shown in FIGS. 15–17, one or more clips 180 are desirably attached tothe table top 12 and the clips are sized and configured to hold the legs62, 64 in the collapsed or storage position. In particular, as seen inFIG. 3, the clips 180 receive and retain the legs 62, 64 such that thelegs are generally parallel to and proximate the lower surface 16 of thetable top 12. Desirably, at least a portion of the legs 62, 64 arelocated within the channels 72 formed in the lower surface 16 of thetable top 12 so that the height of the table top can be minimized whenthe legs are in the collapsed position. As shown in FIG. 3, a singleclip 180 may be used to receive and retain each leg 62, 64 in thecollapsed position. It will be appreciated, however, that any suitablenumber of clips 180 may be used to retain the legs 62, 64 in thecollapsed position. It will also be appreciated that the table 10 doesnot require the clip 180 to secure the legs 62, 64 in the collapsedposition and other suitable devices may be used to secure the legs inthe collapsed position. For example, one or more securing members asdisclosed in Assignee's U.S. Pat. No. 6,530,331, entitled PortableFolding Utility Table with Integral Receiving Members, which is herebyincorporated by reference in its entirety, may be used to secure thelegs in the collapsed position.

The clip 180 includes a body 182 that is sized and configured to beinserted into a corresponding receiving portion 184 formed in the tabletop 12, and the receiving portion desirably has the same general sizeand shape as one of the depressions 30. Thus, while the receivingportion 184 may be placed in any suitable location, it is desirablypositioned so that it does not interrupt or disturb the generallyuniform pattern of depressions 30. Accordingly, the receiving portion184 may allow the table top 12 to be constructed with generally uniformcharacteristics, such as generally consistent strength and structuralintegrity, because the receiving portion may act or function similar toone of the depressions 30.

As best seen in FIGS. 16 and 17, the clip 180 includes a leg receivingportion 186 that is sized and configured to receive and retain a leg 62,64 of the table 10. The leg receiving portion 186 preferably receivesand retains the leg 62, 64 in a snap, friction or interference fit. Inparticular, the leg receiving portion 186 includes an opening 188 thatis smaller than the corresponding portion of the leg 62, 64 that isintended to be received by the receiving portion. Thus, when the leg 62,64 is inserted into the opening 188, the clip 180 deforms to increasethe size of the opening and allow the leg to be inserted into the legreceiving portion 186. The clip 180 then elastically or resilientlyreturns to its original position to receive and retain the leg 62, 64within the leg receiving portion 186.

The clip 180 also includes a retaining portion 190 that allows the clipto be connected to the table top 12. The retaining portion 190 has agenerally U-shaped configuration with opposing sidewalls 192, 194 and alower surface 196. The opposing sidewalls 192, 194 include outwardlyextending projections 198, 200, respectively, that are sized andconfigured to securely connect the clip 180 to the table top 12. Inparticular, as best seen in FIG. 17, the receiving portion 184 formed inthe table top 12 includes an opening 202 that is desirably sized smallerthan at least a portion of the width of the retaining portion 190 of theclip 180. When the retaining portion 190 of the clip 180 is insertedinto the opening 202, the retaining portion and/or the opening deform ordeflect to allow the retaining portion to be inserted into the receivingportion 184. The opening 202 and/or the retaining portion 190 thenresiliently or elastically return to there original positions to securethe clip 180 within the receiving portion 184.

Additionally, the receiving portion 184 includes opposing sidewalls 204,206 and a bottom surface 208 and at least a portion of these surfacesare intended to contact corresponding portions of the clip 180.Specifically, the sidewalls 204, 206 of the receiving portion 184 aredesigned to contact the sidewalls 192, 194 of the retaining portion 190of the clip 180, and the projections 198, 200 are intended to bite intoand engage the sidewalls of the receiving portion. The relatively largecontact area between the retaining portion 190 of the clip 180 and thereceiving portion 184 in the table top 10, and the engagement of theprojections 198, 200 with the sidewalls 204, 206 of the receivingportion, allows the clip to be securely connected to the table top 12.

Advantageously, the clips 180 can be quickly and easily connected to thetable top 12, which may speed the manufacturing process. The clips 180also allow the legs 62, 64 to be secured in the collapsed positionregardless of the position or orientation of the table 10. In addition,the clips 180 may be disconnected from the table top 12, if desired.Significantly, the clips 180 can be attached to the table top 12 withoutthe use of mechanical fasteners such as screws or bolts, but mechanicalfasteners may be used to attach the clips to the table top if desired.Further, it will be appreciated that the clips 180 may have othersuitable sizes and configurations depending, for example, upon the sizeand configuration of the receiving portion 184 formed in the table top12. Other suitable embodiments for the clip are disclosed in Assignee'sco-pending U.S. patent application Ser. No. 10/409,259, filed Apr. 8,2003, entitled Frame That Can Be Attached to a Table Top withoutMechanical Fasteners, which was previously incorporated by reference inits entirety.

As shown in FIGS. 2, 3 and 18, the lip 28 is preferably disposed near orat the outer portion of the table top 12. As discussed above, the lip 28preferably extends downwardly beyond the lower surface 16 of the tabletop 12 and the lip may be aligned with or form part of the edge 26 ofthe table top, but the lip may also be spaced inwardly from the edge ofthe table top. As best seen in FIG. 18, the lip 28 includes an innersurface 210 and a lower surface 212, and the lip preferably has agenerally hollow interior. Advantageously, the lip 28 may be integrallyformed during the blow-molding process as part of a unitary, one-piecetable top 12. It will be appreciated, however, that the lip 28 does nothave to be formed as a unitary component of the table top 12.

The lower surface 212 of the lip 28 desirably has a smooth, planarsurface that facilitates stacking of the tables 10. The inner surface210 of the lip 28, however, includes a number of serrations, notches,ribs, and/or struts that are sized and configured to increase thestrength, rigidity and/or flexibility of the lip 28. In particular, theinner surface 210 of the lip 28 may include a number of notches,indentations, grooves or other inwardly extending portions 216 to forman uneven or saw-tooth type surface. The inner surface 210 may alsoinclude a number of bumps, humps, protrusions or other outwardlyextending portions 218 to form an uneven or saw-tooth type surface. Theinner surface 210 of the lip 28 may also contain a combination ofinwardly and outwardly portions 216, 218 to form the uneven or saw-toothtype surface.

Advantageously, the uneven inner surfaces 210 of the lip 28 may increasethe strength, rigidity and/or flexibility of the lip 28, which mayincrease the strength, rigidity and/or flexibility of the outer portionsof the table top 12. For example, the uneven inner surfaces 210 of thelip 28 may allow the outer portions of the table top 12 to absorb moreenergy or larger impacts than conventional planar surfaces.Additionally, the uneven inner surfaces 210 of the lip 28 may absorbmore energy without deforming and the uneven inner surfaces 210 may flexor deflect more without breaking or permanently deforming. Further, theuneven inner surfaces 210 may be more likely to resiliently return tothere original configurations. Thus, the serrated inner surfaces 210 ofthe lip 28 may form a more durable and longer-lasting outer portion ofthe table top 12.

The lip 28 may also include one or more ribs 220 that increase the wallthickness of the inner surface 210 of the lip. Advantageously, the ribs220 may also increase the strength, rigidity and/or flexibility of theouter portions of the table top 12. The ribs 220 preferably extend fromthe lower surface 16 of the table top 12 to the lower surface 212 of thelip 28 and the ribs are preferably generally vertically aligned, but theribs may have any suitable arrangement and configuration. It will beappreciated that the ribs 220 may be used in combination with theinwardly extending portions 216 and/or the outwardly extending portions218 to increase the strength of the table top 12. Further, it will beappreciated that the inwardly extending portions 216, outwardlyextending portions 218 and/or ribs 220 may be located in other suitableportions of the table top 12, such as the outer surfaces of the lip, theedge 22 of the table top 12, and/or the lower surface 212 of the lip. Itwill be understood, however, that the table top 12 does not requireinwardly extending portions 216, outwardly extending portions 218 orribs 220 be formed in the inner surface of the lip 28.

Significantly, the inwardly extending portions 216, outwardly extendingportions 218 and/or ribs 220 may be positioned such that they aregenerally consistent with the pattern of depressions 30 formed in thelower surface 16 of the table top 12. That is, the inwardly extendingportions 216, outwardly extending portions 218 and/or ribs 220 may belocated so that they are aligned with the pattern of depressions 30 tocreate a table top 12 with more uniform characteristics. This may allowa table top 12 to be constructed with generally consistent strength andstructural integrity.

Further, as best seen in FIG. 18, one or more of the corners 222 of thetable top 12 may have one or more inwardly extending portions 216,outwardly extending portions 218 and/or ribs 220 to increase thestrength and structural integrity of the corner. The inwardly extendingportions 216, outwardly extending portions 218 and/or ribs 220 may bespaced closer together in the corners 222 than along the inner surface210 of the lip 28, if desired, to further increase the strength andstructural integrity of the table top. The inwardly extending portions216, outwardly extending portions 218 and/or ribs 220 may beparticularly advantageous in the corners 222 because the corners may bemore likely to be damaged and the curved surfaces of the corners mayhave less strength than the straight edges of the table top 12.

In order to further increase the strength and structural integrity ofthe corners 222, the radius of the corners may be increased because thestrength and structural integrity of the corners increases with a largerradius of curvature. Preferably, the radius of curvature of the innersurface of the corner 222 is increased and one or more inwardlyextending portions 216, outwardly extending portions 218 and/or ribs 220are formed in the corner for added strength. It will be appreciated thatthe inwardly extending portions 216, outwardly extending portions 218and/or ribs 220 may also be formed on the outer surfaces of the corners222 and/or the other edges of the table top 12. Other suitableembodiments for a table top with inwardly extending portions, outwardlyextending portions and/or ribs are disclosed in Assignee's co-pendingU.S. patent application Ser. No. 10/409,273, filed Apr. 8, 2003,entitled Edge and Corner for a Table Top, which is hereby incorporatedby reference in its entirety.

As seen in FIGS. 2 and 3, the inner surface 210 of lip 28 may alsocontain one or more handles 224 that are integrally formed in the tabletop 12. The handles 224 allow the table 10 to be easily carried when thelegs 62, 64 are in the collapsed position. In particular, the handles224 are preferably sized and configured to allow the user to grip thetable 10 with one hand and the handles are preferably located at or nearthe center of the table top 12. The handles 224 are preferablyintegrally formed in the lip 28 of the table top 12 so that thegenerally consistent pattern of depressions 30 in the lower surface 16of the table top is not disturbed, but the handles may be formed in anydesired portion of the table top. Additionally, while the handles 224are preferably integrally formed in the table top 12 as part of aone-piece blow-molded structure, the handles do not have to beintegrally formed in the table top.

Significantly, the lip 28, inwardly extending portions 216, outwardlyextending portions 218, ribs 220 and handles 224 may be integrallyformed in the table top 12 as part of a unitary, one-piece structure.Desirably, these features are integrally formed in the table top 12during the blow-molding process. It will also be understood that otherfeatures of the table top 12 may be integrally formed as part of aone-piece structure. For example, the depressions 30, frame mountingportions 36, bracket mounting portions 110, and clip receiving portions184 may be integrally formed as part of the one-piece structure. Becausethese features may be integrally formed in the table top 12, that mayexpedite the manufacturing process. These features, however, do not haveto be integrally formed in the table top 12 and they could be attachedto the table top by any suitable methods or devices.

As seen in FIGS. 19 and 20, the table top 12 may also be constructedfrom two or more pieces. In particular, the table top 12 may beconstructed from a first piece 230 and a second piece 232 with one ormore interlocking portions 234 and one or more overlapping portions 236to create the table top 12 that folds in half. Significantly, the tabletop 12 that folds in half may allow the table 10 to be easilytransported and/or stored. Additionally, the various features discussedabove can be integrally formed in the table top 12 constructed from twoor more pieces. It will be appreciated, however, that the table top 12does not have to be constructed from two or more pieces. Other suitableembodiments for a table top that is foldable are disclosed in Assignee'sco-pending U.S. patent application Ser. No. 10/408,914, filed Apr. 8,2003, entitled Portable Folding Table, which is hereby incorporated byreference in its entirety.

Although this invention has been described in terms of certain preferredembodiments, other embodiments apparent to those of ordinary skill inthe art are also within the scope of this invention. Accordingly, thescope of the invention is intended to be defined only by the claimswhich follow.
